LVS series in conventional starts to work from 125-150v but looking at current situation...
150v pe baki kuch nai chalta..lol...150v means you had a damn big fault or broken neutral...
so technically with 150v you would still be reluctant to use fridge bcz its actually unstable and nothing else will work
banda not complaining to fix fault why bcz 150V pe fridge ac chalta ha
karachi users used to face it alot but after severe years of up gradation...your 99% actual voltages would vary from 225-235v +/-5 unless you had broken neutral from service wire or internally
